Hi @Anonymous :

I assume there is a file list:

ClearCollect( Gallerylist, {FileName:"DocumentName"}, {FileName:"DocumentName_1"}, {FileName:"DocumentName_2"} )

I assume there is a text input control(TextInput9) to input file name

You could use this formula to set the file name:

If( IsEmpty(Filter(Gallerylist,First(Split(FileName,"_")).Result=TextInput9.Text)), TextInput9.Text, TextInput9.Text&"_"&Max(ForAll(Filter(Gallerylist,First(Split(FileName,"_")).Result="DocumentName"),Value(Last(Split(FileName,"_")).Result)),Value)+1 )

Best Regards,

Bof
